    - #### setCurrentThread

          public void setCurrentThread(boolean isCompletionListener)

      Sets current thread to the context

      Meant to inform an JMSContext which is the thread that CANNOT call some of its methods.

      Parameters:
        `isCompletionListener` - : indicating whether current thread is from CompletionListener or from MessageListener.

    - #### clearCurrentThread

          public void clearCurrentThread(boolean isCompletionListener)

      Clear current thread from the context
      Parameters:
        `isCompletionListener` - : indicating whether current thread is from CompletionListener or from MessageListener.

    - #### assertNotCompletionListenerThreadRuntime

          public void assertNotCompletionListenerThreadRuntime()

      Asserts a `CompletionListener` is not calling from its own `JMSContext`.

      Note that the code must work without any need for further synchronization, as there is the requirement that only one CompletionListener be called at a time. In other words, CompletionListener calling is single-threaded.

      See Also:
        `JMSContext.close()`, `JMSContext.stop()`, `JMSContext.commit()`, `JMSContext.rollback()`

    - #### assertNotCompletionListenerThread

          public void assertNotCompletionListenerThread()
                                                 throws javax.jms.IllegalStateException

      Asserts a `CompletionListener` is not calling from its own `Connection` or from a `MessageProducer` .

      Note that the code must work without any need for further synchronization, as there is the requirement that only one CompletionListener be called at a time. In other words, CompletionListener calling is single-threaded.

      Throws:
        `javax.jms.IllegalStateException`
      See Also:
        `Connection.close()`, `MessageProducer.close()`

    - #### assertNotMessageListenerThreadRuntime

          public void assertNotMessageListenerThreadRuntime()

      Asserts a `MessageListener` is not calling from its own `JMSContext`.

      Note that the code must work without any need for further synchronization, as there is the requirement that only one MessageListener be called at a time. In other words, MessageListener calling is single-threaded.

      See Also:
        `JMSContext.close()`, `JMSContext.stop()`

    - #### assertNotMessageListenerThread

          public void assertNotMessageListenerThread()
                                              throws javax.jms.IllegalStateException

      Asserts a `MessageListener` is not calling from its own `Connection` or `MessageConsumer`.

      Note that the code must work without any need for further synchronization, as there is the requirement that only one MessageListener be called at a time. In other words, MessageListener calling is single-threaded.

      Throws:
        `javax.jms.IllegalStateException`
      See Also:
        `Connection.close()`, `MessageConsumer.close()`
